The airspeed indicator asi or airspeed gauge is a flight instrument indicating the airspeed of an aircraft in kilometers per hour km h knots kn miles per hour mph and or meters per second m s. The recommendation by icao is to use km h however knots is currently the most used unit the asi measures the pressure differential between static pressure from the static port and total.

Air velocity meters use vane cup hot wire or differential pressure technology to measure the speed and or volume of air movement.

However since indicated airspeed only shows true speed through the air at standard sea level pressure and temperature a tas meter is necessary for navigation purposes at cruising altitude in less dense air.

They are commonly found in weather stations but are also important tools for analyzing ventilation systems aerodynamics testing hvac balancing fume hood verification and other applications in which the movement of air is a primary concern. On jet airliners the tas meter is usually hidden at speeds. The ias meter reads very nearly the tas at lower altitude and at lower speed.
